Description

A billet output shaft designed as a serious upgrade for 1989–2003 Ford 7.3L Powerstroke transmissions. It's built from aerospace-grade alloy to handle high torque, heavy loads, and aggressive driving, preventing breakage that stock shafts might experience. Precision machined for a perfect fit, it supports powerful builds and adds drivetrain reliability.
